I use a digital business card with a QR code that gives the user an option to add my contact information to their device; it includes a link to my website. I wish there was a way to include a second QR code that opens my site in the user's browser.
I would use an actual printed business card with the digital business card as a supplement.
The business card is easy to hand over, but that is a low-quality contact, in my opinion, because the card can easily be lost, dropped, or thrown out.
With digital business cards, I ask the person for permission, making it more active. However, I can see how my contact can easily be lost. If I don't follow up and stay in contact in some way.
